Instructions
Jam Preparation: In a medium-sized pot, combine blackberries, honey, lemon juice, and lavender. Bring to a boil, then mash the berries. Continue cooking until the jam is thickened by about 1/3. Cool to thicken further.
Cake Preparation: Preheat oven to 350°F and line a 9×13 inch baking dish with parchment paper. In a large bowl, mix coconut oil, sour cream, eggs, sugar, and vanilla. Gradually add flour, baking soda, baking powder, and salt. Mix in milk until smooth.
Baking: Pour batter into the pan. Dollop 1/2 to 3/4 cup jam over the batter and swirl lightly with a knife. Bake for 30-35 minutes. Cool completely.
Frosting: Beat butter and powdered sugar until fluffy. Incorporate white chocolate and vanilla. Spread a thin jam layer on the cake, then frost. Swirl extra jam into the frosting.
